Benefits of technology

The steerable extension with a rear-viewing imaging device enhances the viewing field, allows greater movement, and reduces procedure time and patient discomfort by enabling better visualization of areas behind folds and flexures, improving the accuracy and safety of medical procedures.

Problems solved by technology

Repositioning and movement of the endoscope prolongs the procedure and causes added discomfort, complications, and risks to the patient.
Additionally, in an environment such as the lower gastro-intestinal tract, flexures, tissue folds and unusual geometries of the organ may prevent the endoscope's camera from viewing all areas of the organ.
The unseen area may cause a potentially malignant (cancerous) polyp to be missed.

Embodiment Construction

[0039]FIG. 1 illustrates a first exemplary endoscope 10 of the present invention. This endoscope 10 can be used in a variety of medical procedures in which imaging of a body tissue, organ, cavity or lumen is required. The types of procedures include, for example, anoscopy, arthroscopy, bronchoscopy, colonoscopy, cystoscopy, EGD, laparoscopy, and sigmoidoscopy.

[0040]The endoscope 10 of FIG. 1 may include an insertion tube 12 having a main imaging device 26 at its distal end (FIG. 2), a control handle 14 connected to the insertion tube 12, and a secondary imaging device 30 positioned at the distal end of the endoscope 10.

[0041]The insertion tube 12 of the endoscope 10 may be detachable from the control handle 14 or may be integrally formed with the control handle 14. The diameter, length and flexibility of the insertion tube 12 depend on the procedure for which the endoscope 10 is used.

[0042]As shown in FIG. 2, the insertion tube 12 preferably has one or more longitudinal channels 22 ...

Abstract

An endoscope includes an insertion tube having a distal end and an imaging device with a steerable extension. The proximal end of the extension is attached to the distal end of the insertion tube. An endoscope includes an insertion tube having a distal end region and a rear-viewing imaging device at least partially disposed inside the distal end region. An endoscope includes an insertion tube having a distal end cap, an imaging device, and a link that couples the imaging device to the distal end cap of the insertion tube.
